Hi Md M,
I'm Tim, an Independent Consultant here and a Microsoft user like you. I don't work for Microsoft and do not have access to any of your data on their system.
In the newer versions of MS Word, including Word Online, the process of removing add-ins may vary slightly.
Here's a general method you can try if different to the one already carried out:-
- Open your Word document.
- Click on the "Insert" tab in the top menu.
- Look for the "Add-ins" group, which may be located under a different tab such as "Home" or "Insert."
- Click on the "Add-ins" button or a similar option that opens the add-in pane or task pane.
- In the add-in pane, you should see a list of installed add-ins. Locate the add-in you want to remove.
- Look for an option like "Manage My Add-ins" or a gear/settings icon associated with the add-in.
- Click on that option or icon, and you should find a "Remove" or "Delete" option.
- Confirm the removal when prompted.
I hope this information helps. If you have any questions, please let me know and I'll be glad to assist you further or If you find it helpful, you can mark this comment as the answer.
Kind regards
